specialization of cells

Simple epithelium may sometimes become modified for some specific functions. Two such modifications are very common, namely, ciliated epithelium and glandular epithelium. Ciliated epithelium is always a modification of columnar epithelium. Here, the cells are characterized by the presence..

Spontaneous redox reactions are the metal displacement reactions. Therefore such reactions have been used for producing electricity. This is done by carrying out these reactions in specially designed units called electrochemical cells. An electrochemical cell is a dev..

It is represented by loosely arranged parenchyma cells found in between the vascular bundles. The cells are specialized for storage of wate..

The epithelial cells become specialized to form receptors that are capable of receiving the various external and internal stimuli, and transferring them to the nerve cells. E.g. Photoreceptors, thermoreceptors, osmoreceptors, pressure receptor..

These are special sclerenchymatous cells found in the cortex, pith, phloem, hard seeds, nuts and stony fruits. The flesh of pear and guava are sometimes gritty due to the presence of sclereids. These cells are thick walled, hard and strongly lignified. They are isodiam..

Differentiation - Differentiation is the process by which the unspecialised embryonic cells change in structure and function during development and growth of an organism to form specialised cell types, tissues, and organs, distinct from one another. Differentiation makes ce..
